1

Clinical signs that are very important:

Salivation
Lameness
Colic symptoms
Nervous signs

2

Pigs industry we have few opportunities to be examined:

Temperature can be checked, clinical examination by watching carefully.
Teething, breath and coughs can be seen.
Necroscopy are very important – base your diagnostic on this.

3

CLINICAL SIGN EXAMPLES THAT WE HAVE TO CHECK FOR:

Daily weight gain
High temperature
Cough

4

High fever can indicate

CSF, ASF (classical and African swine fever) NOTIFIABLE
or Erysipelas - Not notifiable, but ZOONOSIS

5

High fever and cough can indicate

If CSF and ASF are excluded we can check for actinobacillus which is not notifiable, but cause severe pneumonia – not zoonosis.

6

TRACHEAL diseases

Pneumonia
Trachitis
bronchitis
microbronchitis

7

MYCOPLASMA HYOPNEUMONI

Door opener/key factor of the Swine respiratory disease complex - SRDC
You see many neutrophils, monocytes, many cells!
Lung like palpations
Secondary bacteria’s can come.

8

Porcine respiratory and reproduction virus

great importance! Notifiable in Hungary!
Many import piglets and Hungary try to check them for this virus and sends them back if they are infected.
Spreading by air, must be transported in special transport because of this.
There is vaccines, be careful with the live vaccine, it can spread. Both inactivated and live vaccine has pros and cons.

9

Other important viruses

Foot and mouth disease
CSF
Bovine diseases

10

Circo virus:

Different growth of piglets, some will remain small, but hair is growing. These animals will not survive.
The best is to vaccinate the sow, but with new disease we have to separate these animals and try to treat them.
AB cannot be fulfilled, sometimes we have to cull all the animals.

11

Aujeszky’s disease

Many European countries are free from it.
Every age groups
Sows abort
Piglet clinical nervous system signs
100% dies
Influenca like clinical signs – respiratory problems.
If a farm has it – cats disappear, they are susceptible for the virus. (lethal)

12

MICROTOXINS

B1 – Fumonisin toxins

13

B1 – Fumonisin toxins

Free contact in thorax.
Heavy breathing, inspirational type is the main clinical sign.
Necropsy – watery like contact, coagulate with air.

14

BACTERIA

Actinobacillus pleuropneumonei (?)

15

Actinobacillus pleuropneumonei (?)

High fever always.
Rapid course of disease – dead in the end of the days
Bloody foamy nasal discharge – this infect other

Important
Promt interaction – the whole group should be treated with AB
Organize a chance of stopping the infection, vaccinate and working clothes must be changed.
Everything should be cleaned every night and morning, stop the way of infection.
